    • Constructor Detail

      • PcapWriteHandler

        public PcapWriteHandler​(java.io.OutputStream outputStream)
        Create new PcapWriteHandler Instance. captureZeroByte is set to false and writePcapGlobalHeader is set to true.
        Parameters:
        outputStream - OutputStream where Pcap data will be written. Call close() to close this OutputStream.
        Throws:
        java.lang.NullPointerException - If OutputStream is null then we'll throw an NullPointerException

      • PcapWriteHandler

        public PcapWriteHandler​(java.io.OutputStream outputStream,
                        boolean captureZeroByte,
                        boolean writePcapGlobalHeader)
        Create new PcapWriteHandler Instance
        Parameters:
        outputStream - OutputStream where Pcap data will be written. Call close() to close this OutputStream.
        captureZeroByte - Set to true to enable capturing packets with empty (0 bytes) payload. Otherwise, if set to false, empty packets will be filtered out.
        writePcapGlobalHeader - Set to true to write Pcap Global Header on initialization. Otherwise, if set to false, Pcap Global Header will not be written on initialization. This could when writing Pcap data on a existing file where Pcap Global Header is already present.
        Throws:
        java.lang.NullPointerException - If OutputStream is null then we'll throw an NullPointerException
